This type will be used in a following commit.
This type was not previously used by git. This can cause trouble for people on systems without struct itimerspec if they only rely on config.mak.uname. They will need to set NO_STRUCT_ITIMERSPEC manually.

This patch can be improved by finding out which systems doesn't have struct itimerspec and adding entries for them to config.mak.uname.
